a.        Install controllers implementing a demand-limiting strategy consistent with the Sequences of Operation Guideline available at "Enterprise Utility Management System (EUMS) Equipment Control Strategies", on the PSU Design Standards website.  The demand-limiting strategies shall be submitted, reviewed and approved by the University’s Physical Plant BAS Group prior to implementation.
2.           Time Scheduling
a.        The system shall be capable of scheduling by individually controlled equipment and groups of individually controlled equipment.  Each schedule shall provide beginning and ending dates and times (hours:minutes).  The CSC shall provide a BACnet BV for scheduling by the CSC.
3.                Reset (Source Temperature Optimization (STO))
a.                    The system shall automatically perform source optimization for all air handling units, chillers and boilers in response to the needs of other downstream pieces of equipment, by increasing or decreasing supply temperature setpoints, i.e. chilled water, discharge air, etc. using University defined parameters. In addition to optimization, the STO capability shall also provide for starting and stopping primary mechanical equipment based on zone occupancy and/or zone load conditions.
b.                    The STO program will allow setpoints for various equipment in the heating/cooling chain to be reset between an University defined maximum and a minimum setpoint based on the actual requirements of the building zones.  The actual setpoint shall be calculated based on the number of heating or cooling requests which are currently being received from the equipment or zones served.  Once every update period, the STO program surveys the network to see if any piece of equipment requires any additional heating or cooling from its source.
c.                     As an example, a VAV air handler is the source of cold air for a number of VAV boxes. Assume that the STO program for the air handler has the following parameters established for it by the University’s Physical Plant BAS Group:

1)          Optimized setpoint description:  Initial setpoint 60.00, Max. setpoint 65.00, Min. setpoint 55.00. Every 2.0 minutes, trim by 0.25 and respond by -0.50 but no more than 2.0 . Every two minutes, the STO program will total up all of the requests and calculate a new setpoint:. New setpoint = prev setpoint  + 'trim by' + ('respond by' x no. of  req.). Assuming four requests were received and the previous setpoint was 57.00 degrees, the new setpoint would be:  New setpoint = 57.00 + 0.25 + (-0.50 x 4) = 55.25 Deg F

2)          If the number of requests received multiplied times the 'respond by' value is greater than the   'but no more than' value, the 'but no more than' value is used inside the parenthesis in the above calculation.

4.                Set Back /Set Up (Day/Night Setback (DNS))
a.              The system shall allow the space temperature to drift down or up within a preset (adjustable) unoccupied temperature range.  The heating or cooling shall be activated upon reaching either end of the DNS range and shall remain activated until the space temperature returns to the DNS range.
b.              The system shall be capable of closing all outside air and exhaust air dampers during the unoccupied period, except for 100% outside air units.
c.               Unoccupied space temperature shall be monitored by the DDC temperature sensors located in the individual zones being controlled or within a representative room in the building if full DDC control is not being effected.
d.              User shall be able to define, modify or delete the following parameters:

1)                      DNS setpoint temperature(s)

2)                      Temperature band for night heating operation

3)                      Period when the DNS is to be activated

5.                Timed Local Override (TLO)
a.              The system shall have TLO input points/objects which permit the occupants to request an override of equipment which has been scheduled OFF. The system shall turn the equipment ON upon receiving a request from the local input device. Local input devices shall be push button (momentary contact), wind-up timer, or ON/OFF switches as detailed in the Object Table(s).
b.              If a push button is used the system operator shall be able to define the duration of equipment ON time per input pulse and the total maximum ON time permitted. Override time already entered shall be canceled by the occupant at the input point. If a wind-up timer is used the equipment will stay in override mode until the timer expires. Year to date, month-to-date and current day override history shall be maintained for each TLO input point. History data shall be accessible by the operator at any time and shall be capable of being automatically stored on hard disk and/or printed on a daily basis.
6.                Space Temperature Control (STC)
a.              There shall be two independently-adjustable space temperature setpoints, one for cooling and one for heating, separated by a dead band. Only one of the two setpoints shall be operative at any time. The cooling setpoint is operative if the actual space temperature has more recently been equal to or greater than the cooling setpoint. The heating setpoint is operative if the actual space temperature has more recently been equal to or less than the heating setpoint. There are two modes of operation for the setpoints, one for the occupied mode (example: heating = 72 degrees F, cooling = 76 degrees F and one for the unoccupied mode (example: heating = 55 degrees, cooling = 90 degrees F).  NOTE: it will no longer be acceptable to accomplish having a Heating Setpoint and a Cooling Setpoint by having a single mid-range setpoint with offsets.
b.              The occupied/unoccupied modes may be scheduled by time, date, or day of week via a BACnet BV.
c.               All setpoints and offsets shall be operator definable. When in the occupied mode, start-up mode, or when heating or cooling during the night setback unoccupied mode, a request shall be sent over the network to other equipment in the HVAC chain, such as to an AHU fan that serves the space, to run for ventilation. The operator shall be able to disable this request function if desired.
d.              The cooling and heating setpoints may be increased (decreased) under demand control conditions to reduce the cooling (heating) load on the building during the demand control period. Up to three levels of demand control strategy shall be provided. The operator may predefine the amount of setpoint increase or decrease for each of the three levels. Each space temperature sensor in the building may be programmed independently.
e.              An optimum start-up program transitions from the unoccupied setpoints to the occupied setpoints.  The optimum start-up algorithm considers the rate of space temperature rise for heating and the rate of space temperature fall for cooling under nominal outside temperature conditions; it also considers the outside temperature; and the heat loss and gain coefficients of the space envelope (AI: Space Temperature).
f.                 A PID control loop, comparing the actual space temperature to its setpoint, shall modulate the dampers and heating coil valve or heating stages in sequence to achieve the setpoint target.
7.                Historical Data and Trend Analysis :  A variety of Historical data collection utilities shall be provided to automatically sample, store, and display system data in all of the following ways.
a.              Continuous Point Histories: Global Building Controllers /Routers shall store Point History Files for all analog and binary inputs and outputs.  The Point History routine shall continuously and automatically sample the value of all analog inputs at half hour intervals.  Samples for all physical hardware input and output points shall be collected during the warranty period, to allow the user to immediately analyze equipment performance and all problem-related events. Point History Files for binary input or output points and analog output points shall be archived on the server workstation hard drive.
b.              Control Loop Performance Trends: Global Building Controllers /Routers shall also provide high resolution sampling capability with an operator-adjustable resolution of 10-300 seconds in one-second increments for verification of control loop performance.
c.               Extended Sample Period Trends:  Measured and calculated analog and binary data shall also be assignable to user-definable trends for the purpose of collecting operator-specified performance data over extended periods of time.  Sample intervals of 1 minute to 2 hours, in one-minute intervals, shall be provided.  Each standalone Global Building Controller /Router shall have a dedicated buffer for trend data, and shall be capable of storing a minimum of 5000 data samples.
d.              Data Storage and Archiving:  Trend data shall be stored at the Global Building Controllers /Routers, and uploaded to hard disk storage when archival is desired.  Uploads shall occur based upon either user-defined interval, manual command, or when the trend buffers become full.  All trend data shall be available in disk file form for use in 3rd Party personal computer applications.
8.                Runtime Totalization: Global Building Controllers /Routers shall automatically accumulate and store runtime hours for binary input and output points as specified.
a.              The Totalization routine shall have a sampling resolution of one minute or less.
b.              The user shall have the ability to define a warning limit for Runtime Totalization.  Unique, user-specified messages shall be generated when the limit is reached.
9.                Analog/Pulse Totalization: Global Building Controllers /Routers shall automatically sample, calculate and store consumption totals on a daily, weekly, or monthly basis for user-selected analog and binary pulse input-type points.
a.                    Totalization shall provide calculation and storage of accumulations of up to 99,999.9 units (e.g., KWH, gallons, KBTU, tons, etc.).
b.                    The Totalization routine shall have a sampling resolution of one minute or less.
c.                     The user shall have the ability to define a warning limit. Unique, user-specified messages shall be generated when the limit is reached.
10.            Event Totalization: Global Building Controllers /Routers shall have the ability to count events such as the number of times a pump or fan system is cycled on and off.  Event Totalization shall be performed on a daily, weekly, or monthly basis.
a.              The Event Totalization feature shall be able to store the records associated with a minimum of 9,999,999 events before reset.

b.              The user shall have the ability to define a warning limit. Unique, user-specified messages shall be generated when the limit is reached.

12.                Alarm and Audit Logs
a.          The software shall automatically create audit and alarm logs.
1)          The audit log shall track all actions and changes that are made to the system by any operator.
2)          The alarm log shall keep a record of all alarms that have been generated, acknowledged, deleted, etc.

Notes (apply to Table 1, Table 2, and Table 3)

  1. Select valve CV for 3.0 psi pressure differential with the following exception that the CV shall be a minimum of 1.2.  The basis for this standard is that the characterizing disc opening for those <1.2 CV are too small and raise the potential for flow restriction or total blockage in systems with less than ideal water quality conditions.  Belimo also recommends that valves should be selected for a size no less than 2 nominal sizes of the installed pipe size.
  2. Unless otherwise indicated, valves shall be typically normally closed (NC) fully modulating 2-10 VDC.  Depending on the control application normally open (NO) and modulating with floating point control may be acceptable.  These floating point and the normally closed exceptions require that exceptions shall be reviewed and approved by PSU BAS and Engineering prior to or during the DD (Design Development) phase.  When the floating point option is accepted this does not also waive the requirement for brushless motors.  Belimo TR actuators have motor brushes (in th e floating point option) and are not acceptable.
  3. There may be specific critical applications and/or those with freeze potential where fail-in-place (FIP) is indicated but spring return, fail open or closed should be considered.  Design professional should have this issue reviewed and approved by PSU BAS and Engineering prior to or during the DD (Design Development) phase. 
  4. Freezestat controls shall be hard wired to de-energize 24 VAC power to valve actuator so that valve returns to fail position.
  5. The Design Professional shall refer to HVAC systems design standards and specifications for guidance in determining whether system should be pressure independent or pressure dependent type.  Design Professional shall have this issue reviewed and approved by PSU BAS and Engineering prior to or during the DD (Design Development) phase. 
  6. Belimo Energy Valves shall always be installed at any chilled water coil flowing 200 GPM or greater (with and without a heat exchanger). If the Design Engineer for a specific-Project wants to, they can make a case for implementing an Energy Valve for chilled water coil less than 200 GPM. Energy Valves shall not be used for hot water applications, or for chilled water flowrates less than 20 GPM. Energy valves shall be set to “Position Control”, with Delta-T manager enabled. Delta-T shall be set to the coil design delta-T. Add the BACnet over IP interface to the control system to show valve position feedback, temperatures, and flow. If accessing an IP interface is not feasible, contact the Engineering Services FME (Area Engineer) for the project, making sure to CC fasconstruction@psu.edu to assist with determination.
  7. Steam humidification isolation valve refers to an isolation valve of steam supply serving both humidification control valve and humidification distribution (in the airstream) steam jacketing.
  8. Refer to control sequences for required 2-way (typical) and 3-way specific arrangements.
  9. These applications do not include valves for campus chilled water service.  These valves are typically specified in Utilities specification sections and standards.
  10. For applications not listed above or applications where exceptions should be considered, these valve selections shall be presented by the Professional for review and approval by PSU BAS and Engineering prior to or during the DD (Design Development) phase.

3.8                INSTALLATION OF AIRFLOW MEASUREMENT DEVICES

A.                Installation

1.        Install in accordance with manufacturer’s placement instructions for optimum performance at the locations indicated on the plans.  A written report shall be submitted to the consulting mechanical engineer if any discrepancies are found.

B.                Adjusting

1.        Fan inlet mounted devices may be adjusted during start up and commissioning only after having been checked against known volumetric values (or against another like device measuring the same air volume) at two or more points of operations.

2.        The manufacturer’s authorized representative shall review and approve placement and operating airflow rates for each measurement location indicated on the plans.   A written report shall be submitted to the consulting mechanical engineer prior to installation if any measurement locations do not meet the manufacturer’s placement requirements.  It is recommended that approval for placement wait for the manufacturer’s authorized representative to see the actual installed ductwork.

3.        Field Installation:  Install in accordance with manufacturer’s placement instructions for optimum performance at the locations indicated on the plans.  A written report shall be submitted to the consulting mechanical engineer if any discrepancies are found.

4.        Adjustment:  Duct and plenum devices shall not be adjusted without approval from the consulting mechanical engineer.  Fan inlet mounted devices may be adjusted during start up and commissioning only after having been checked against known volumetric values (or against another like device measuring the same air volume) at two or more points of operation.

PART 4             SEQUENCES OF OPERATION

              This Part shall include Sequences of Operation, Object Tables, and Control Diagrams.
(Contact the University’s Physical Plant BAS Group for Examples.)

 

TIPS for the DESIGN PROFESSIONAL:

1.       Refer to the PSU Design Standards Website for 25 90 00 GUIDE SEQUENCES OF OPERATION 

(LINK: http://www.opp.psu.edu/planning-construction/design_and_construction_standards/division-25-integrated-automation/?searchterm=standard%20sequences%20of%20operation)

 

2.       CntlSpecBuilder   [https://www.ctrlspecbuilder.com/sb/welcome.nsf ]
is recommended as a starting-place if there is not a Guide Sequence already developed by PSU, for the particular System being proposed.  See List of available Guide Sequences below.  Contact BAS Group when Guide Sequences are needed by the Project Team, to receive all the latest versions.  Contact:
oppfasconst@psu.edu .  Using CntlSpecBuilder should provide most of the needed elements (SoO, Object Table, Control Diagram) and get a Sequence of Operation more than 60% complete by selecting optional specifics.  From that point, the Design Professional can further refine and “tweek” the Sequence for the Project-specific application, before Submitting for Design Review at 100% DD.

4.       Be sure to Review Part 3 – EXECUTION requirements of this BAS Guide Spec, to include the requirements of Enhanced Zone Sensors, averaging-type sensors and low-limit duct thermostats in the Mechanical Design documents.

 

5.       Contact Glenn Lelko, PSU Mechanical Engineer, to co-ordinate the sizing & selection of the CHW Choke-valve. And CHW Meter.

 

6.       Be sure to co-ordinate BAS Requirements in Systems by other Disciplines (i.e. Electrical, Plumbing, Elevators, etc.) with the appropriate Design Professional, and Specification Sections.
 

7.       Refer to Division 26 (section 26   09   00) for Lighting Controls requirements.  Contact Engineering Services Electrical Group with any Lighting Controls Questions.

 

 

 

 

Some standard requirements, that are often neglected, include the following.

 

A.      Multiple Sensors              
Multiple Sensors are to be implemented when a piece of Terminal Equipment serves multiple-spaces, such that not more than 2 spaces are represented per one-sensor.  Thus, a VAV serving 3 spaces will have 2 room-sensors networked together.  The Sequence of Operation for the implementation of Multiple-sensors shall be clear that programming shall be selectable between using the High, Low or Average value for controlling the Terminal Equipment that serves the multiple-spaces.  Mechanical Design documents shall indicate locations of “Master” verses “Slave” sensors.

 

B.      Enhanced Zone Sensors (including Set-Point Adjustment, and Timed Local Override) shall be designed for only in private or semi-private Offices, and Conference Rooms.  These shall not be installed in Public Spaces.

 

C.      Outside Air Temperature Sensor (OAT) for Heating System:  An OAT sensor shall be wired directly to the Heating System Controller, in ANY Project with a Heating System.

 

D.      Outside Air Temperature Sensor (OAT) for Cooling System in a Project involving Equipment serving Critical Space(s):  An OAT sensor shall be wired directly to the Cooling System Controller, in ANY Project with Cooling that serves Critical Space(s) (i.e. Animal Rooms, Temperature-critical research, etc.).

 

E.      Weather Station: 
The strategy at PSU-University Park is to have a small quantity of “weather stations”, to best be able to maintain the high-quality sensors.  Consult with the University’s Physical Plant BAS Group if the Design Engineer has a potential need for a “weather station”.  This potential needs considered by the Designer on a Project-specific basis, related to requirements for control based on measurement of: OA Temperature, OA Humidity, OA Local-CO2 and Atmospheric–pressure.  The Designer needs to determine where the Weather Station DATA would come from for this Project.

 

 

 


 

**** NOTE FOR CONSULTANT:  Coordination of these requirements with the Design EE (Electrical Engineer) and appropriate ELECTRICAL Specification Section(s) is ESSENTIAL.  ****
